ELECTROMAGNETIC INTERFERENCE (EMI) ANALYSIS FOR OBLIQUE INCIDENCE OF EM WAVES IN DOUBLE SHIELDS

Reduction of Electromagnetic Interference (EMI), i.e., shielding effectiveness of different shields against the angle of incidence with conductors and conductive polymers using plane - wave theory are carried out. The plane wave shielding effectiveness of new combination of these materials is evaluated as a function of angle of incidence for the double shield. With recent advan cements in synthesizing stable highly conductive polymers, this light - weight, mechanically strong materials appear to be viable alternatives to metals for EMI shielding. The analysis is done at a particular frequency for double shield of different material s
